STEM WINDING AND SETTING MECHANISM FOR WATCHES SPECIPICATIQN formingpart of Letters Patent No. 346,254, dated July 27, 1886.

Application filed January 27, 1886.

To (4 whom it may concern.-

Be it known that I, HENRY ABBOTT, a citi zen of the United States,residing at Newark, in the county ol'EsseX and State of New Jersey, haveinvented certain new and usefulImprovements in Steminding andHand-Setting Watches, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings,which forma part of this specification.

My invention relates to improvements in that class of stem-windingwatches in which the stem-actuated train of wheels and pinions isbrought into or out of engagement with the dial-wheels by the movementendwise of said stem.

It relates, also, to improvements in that class of stem-winding watchesin which the winding and hand-setting mechanism is attached to aseparable plate that is adapted to be removed from the watch withoutdisarranging or separating the parts composing said winding and settingmechanism from each other, for a full description of which reference maybe had to Patent No. 236,748, granted to me 011 January 18, 1881; alsoto recentimprovements on the same, for which I now have applications forpatents pending, parts of which are also shown in the annexed drawings,but are not claimed in this specification.

Myinvention consists in an improved combination and arrangementof parts,and in providing means whereby the class of stem-winding watch-movementsabove referred to are adapted to be used in a class of cases in whichthe winding-crown and push-pin are secured to the case and are adaptedto be moved endwise in the pendant of said ease, for the purpose ofengaging or disengaging said stem with mecl anism for actuating thehands.

It also consists in such an arrangement of the parts composing saidwinding and set ting mechanism as will make the watch-movementinterchangeable and adapted to be read ily placed in any case of theclass above named without adjustment or alteration.

It also consists in providing means whereby the stem-actuated train isautomatically disengaged from the dial-wheels whenever the movement isseparated from the case without Serial No. 189,886. (No model.)

regard to the position which said train last occupied before saidmovement was removed from the case.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a plan view of a portion of awatch-movement and case, showing my improvement as it appears on thedial side of the main plate of the watch. Fig. 2 is a re verse view ofthe same, showing the parts in gear for winding. Fig. 3 is similar toFig. 2, but with the parts in position to set the hands. Fig. 4c isalike view showing the position of from its case. Fig. 5 is a view ofthe main plate of the watch, showing the opening Z) made to receive thebridge D. Fig. 6 is a view of the winding and setting attachment whenseparated from the watch-movement, showing the top of the plate A. Fig.7 is the reverse of Fig. 6. Fig. 8 is the same view as Fig. 7, but withthe bridge D removed. Fig. 9 is an end view of Fig. 6. Fig. 10 is a planview of the bridge D with the spring J attached. Fig. 11 is asectionalview on the line waof Fig. 7. Fig. 12 is an enlarged view: ofthespringJ. Fig. 13 is a view of the leverF. Fig. 14. is an enlarged view of thepinion H, showing the ratchet-teeth on its face. Fig. 15 is a similarview of the sliding clutch G. Fig. 16 is a view of the combinedclutch-lever and spring F. Fig. 17 is a view of the winding crown andpush-pin S, having a male square formed on its inner end. Fig. 18 is aview of the windingstem T, adapted to receive at its outer end a push ofthe style shown in Fig. 17. Fig. 19 is a windingstem, '1, having a malesquare formed at its outer end and adapted to receive a push having akey-pipe at its inner end ofthe form shown in Fig. 20. Fig. 21 is an endview of the winding-stem 22 is a plan view of the winding and settingniechanism of a watch wherein a pivoted yoke, 7, carries a portion ofthe winding-train, showing also the adaptation of my improvement to thisclass of watches, in which view the parts are shown in positionforwinding. Fig. 23 is the same as Fig. 22, but with the parts inposition forsetting the hands. Figs. 2t and 25 the parts when themovement is separated show the reverse and top views, respectively, ofthe winding attachment shown in Fig. 22 when separated from the watch.Fig. 26 is a sectional View on the lineg 3/ of Fig. 24, together with aportion'of the plate B. Fig. 27 is an enlarged view of the pusher S,stem T, and pinion H,of the style employed in Fig. 22. Fig. 28 shows amodified form of the lever E, wherein an anti-friction roller isemployed for the acting surface at 6, instead of the wedgeshape point,as in Fig. 13.

Similar letters of reference refer to like parts in each of the views.

A is the separable plate,to which the winding and setting mechanism isattached; B,the main or pillar plate of the watch; 0, aportion of thewatch-case; D, a bridge covering the crown-wheel R and a portion of thewindingwheel L, and intermediate setting-wheel, M. It also sustains thestem T, on which is journaled the winding-pinion H, and on which alsoslides the clutch G. These wheels and pinion and sliding clutch do notdiffer materially from those usually employed in watches.

F is a clutch-lever pivoted at f, the opposite end of which engages withthe clutch G in an annular groove. It is also provided with the springf, formed of the same piece of metal, the outer end of which bearsagainst a shoulder on the plate A, and tends to hold the ratchet-face ofthe clutch G against that of the pinion I-I.

E is a lever pivoted on the plateA at e'-,and provided at its outer endwith a hook, e, and a wedge-shaped bearing-surface, e, adapted to engagewith and slide over the annular flange t, formed on the outer end of themovementstem T, the inner or opposite end of the lever E engaging withand pressing against the clutch-lever F, except in Figs. 22, 23, 24, 25,

' and 26, where it bears against the stud 5, at-

tached to the yoke 7.

J is aspring adapted to bear against the inner end of the stem T, andtending to force it outward.

P is the main windingwheel over the barrel, and is covered and held inposition by the bridge 8. The movementstem T is adapted at its outer endeither to receive the square arbor or key-pipe of the pusher S,isprovided with a squared portion, t on which slides the clutch G, with around portion, t, on which turns the pinion 1-1, and which,with thepivot '6, forms the bearing-surfaces of the stem T in the bridge D. Thestem T is adapted to receive both a rotary and an endwise movement,being forced outwardly by the spring J, and inward by pressing againstthe crown push-piece S. I

N is an intermediate setting-wheel.

O are the cannon-pinion and minute-wheel, also called dial-wheels.

In Fig. 27 the stem T is shown with the squared portion t extending itsentire length, except where it is flanged at t, and is adapted to slidethrough the square hole extending through the hollow pinion H used inthe style of watch shown in Figs. 22 and 23.

s is a case-spring used in hunting-case watches, and acted upon by ashoulder of the pusher S.

In cases of the class for which these stemwinding movements are adaptedthe pusherS is a fixture of the case, and is arranged to be movedendwise in the neck or pendant of said case within fixed limits, and tobe held therein either at the outer or inner limit of its motion by aspring. The stems are also ordinarily made of standard length. Thesocket, thereforc,in the outer end of the stem T being made of theproper depth to adapt the movement to be used in any one of these cases,itis evident that it may be used in all others of the same class,without alteration or special fitting. v

The operation is as follows: The movement being in its case, the stem Tis forced inward by pressure against the crown-pusher S to the innerlimit of its motion. The flange t on the outer end of the stem T haspassed beyondthe acting-surface e of the lever E. The clutch-leverF,with the aid of its spring f, holds the clutch G and pinion H in closecontact, as shown in Fig. 2. If, now, the crown-push S is rotated in aforward direction, motion will be imparted through the clutch G, pinionH, wheels R L P, and the mainspring will be wound. If the crown-push berotated backward, the ratchet-teeth on the faces of G and H. will slippast each other, and no effect will be produced. If the push S bewithdrawn to the outer limit of its motion, the spring J will force thestem T to follow it outwardly. The annular flange t will slide up theface of the wedge or incline e, causing the lever E to turn on its pivot6 The opposite end of E, bearing against F, will cause G to slide downon the stem T until it engages with M. The pusher S may now be rotatedand the hands turned in either direction, as shown in Fig. 3. If, new,the crown-pusher S be removed entirely from the case, or if thewatch-movement be removed from the case, the stem T will be forcedfarther outward by J until the flange t is caught by the hook e, whichprevents it from falling entirely out of the watch. F is now relievedfrom pressure of the inner end of E, and is free to return the clutch Gto contact with H, as shown in Fig. 4. 7 The watch-movement may be woundin this position while out of its case, if desired, and the time-trainis also relieved from any contact with the setting mechanism, and isfree to run and keep time as well as if in its case.

The action in watches of the pivoted-yoke class, as shown in Figs. 22and 23, is exactly as described, except that the lever E acts upon thestud 5 and turns the yoke 7 on its pivot instead of moving the clutch Gupon the stem. As shown in Fig. 2, after the flange t has passed theacting-surface of 6 there is still suflicient space allowed for pressingthe pusher S still farther in, until the ease-spring s is acted upon bythe shoulder of the pusher. It is evident that the hook 0 might bedispensed with and a screw through D, or other device, employed toprevent the stem T from falling out. It is evident that the form andshape ofE might be modified, if required, without changing its essentialfeatures. It will also be evident that grooves may be employed as anequivalent of the annular flange on the outer end of the stem T. Thespring J may also, if desired, be adapted to act against the flange I,for forcing the stem T outward instead of against its inner end. It isalso evident that the novel forms of stem T, lever E, and spring Jherein shown and described, might with equal facility and advantage beemployed in watches of the more ordinary class, or those wherein thewinding and setting mechanism is attached to the main plate 13, insteadof to the separable plate A. If it is desired to employ theanti-friction roller for the acting-suriace c, as shown in Fig. 28, itwill be desirable also. to make the flange if angular instead ofrounded, as shown in the other figures; but this shape is not essential.

I do not claim, broadly, all of the mechanism herein shown and described5 but the movement-stem T, constructed as shown and described andadapted to co-operate with the case-stem or pusher S, is a novel and anessential feature of this invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. As animprovenient in stemwinding and hand-sctting watches, the rotatable longitudinally movablestem T, mortise-jointed with the pusher S, but not permanently securedthereto, provided with a boss or flange, tand a square or angular body,i in combination with the pusher S and cooperating mechanism, wherebythe watch may be wound or set, substantially as shown and specified.
